GARAGE-DOOR CONTROL MECHANISM.

Application filed April 26,

This invention relates to improvements in garage door control mechanism and more particularly to mechanism for automatically opening and closing the garage doors from points outside the garage and for locking the doors in adjusted position. Means are provided within the garage for rendering inoperative the remote controls when desired.

'A further object is to provide mechanism of this type that is devoid of springs and is positively operated. Simplicity in construction, efliciency and durability are other objects attained.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the claims and illustrated in the accompanying 20 drawings which form a part of this application for patent and in which Fig. 1 is a fragmentary sectional view of a garage equipped with the door control mech anism.

Fig. 2 is an enlarged longitudinal sectional view through the impulse transmitting mechanism for opening the doors.

Fig. 3 is a similar view of that mechanism for closing the doors.

Fig. 4.- is an enlarged fragmentary sectional view illustrating the manually operable impulse transmitting devices located inside the garage.

Fig. 5 is an inside view of the garage 35 illustrating the door control mechanism.

Fig. 6 is a cross section taken on line 66 of Fig. 5.

Fig. 7 is a vertical sectional view taken on line 77 of Fig. 5, enlarged.

- Fig. 8 is an end view of Fig. 6 with the movable parts in an altered position.

Like reference characters denote corresponding parts throughout the several views. 7

The present invention is designed as an improved form of the invention shown in my United States Patent on platform operated garage door latch, No. 1,652,574, issued Dec. 13, 1927.

In large cities itis particularly desirable that the doors of ones garage be provided with remote control mechanism so thatthe interior of the garage can be examinedat a distance to determine whether any unau- 1928. Serial No. 272,988.

thorized person, a tramp, burglar orthe like, has secreted himself therein during the absence of the owner or occupant. When arriving late in the night the doors can be swung open from a remote point and the interior of the garage illuminated by the vehicle spot light or headlights. In inclement weather the mechanism is also very convenient and serviceable.

The reference numeral 1 denotes the garage provided with the outwardly swinging hinged doors 2, the meeting edges of which may be straight as shown in Fig. 6 or they may be rabbeted as shown in the patent above mentioned. The floor of the garage is denoted by the numeral 3 and the yard or private property of the garage owner contiguous to the garage by the numeral 4:. Secured to a cross member 5 at the top of the doors that extends inwardly therefrom are the gear brackets 6, 7, the former carrying a gear 8 and a toothed segment 9 in mesh therewith, the axis of said gear 8 extending downwardly to form the extension 10. .The

bracket 7 carries the toothed segment 11 and the gears 12, 13 in mesh with each other as clearly shown in Figs. 5 and 6, the axis of the gear 13 being extended downwardly beyond the bracket to form the extension 14.

Beach or connecting rods 15 and 16 have their remote ends fastened respectively to the segments 9 and 11 upon one side of the axes thereof, the inner or adjacent ends of said rods forming eyes 17, 18 that are engaged and connected together by the adjusting bolt 19, a certain amount of play or relative movement of the reach rods being permitted by said bolt.

Similar reach rods 20, 21 arranged upon the opposite side of the axes of the segments 9, 11 have their remote ends secured thereto, the inner or adjacent ends of said rods forming eyes 22, 23 that are connected by the adjusting bolt 24.

The rod 15 at a point contiguous to the segment 9 is connected by a link 25 to a hook 26 that is carried by a cable 27 that passes over a sheave 28 arranged in a bracket 29 arranged upon the door jamb, said cable passing down and into engagement with a sectional hand lever 30 fulcrumed to a bracket 31 secured to the door jamb, the sections of said lever being separably secured together by the nut 32 and one section thereof carrying an eye bolt 33 to which the cable 34 is connected that passes through the floor 3 into a submerged casing 35 and about a sheave 36 arranged therein and out through a conduit 37 communicating therewith and extending through or beneath the garage wall to and into the housing 38 submerged in the ground adjacent the garage, the top portion of said housing being flush with the ground level and having hinged thereto the cover-like trigger 39, the non-hinged end thereof being enlarged and adapted to telescope into the side walls of the housing, said trigger having secured thereto one end of the cable 27 that, after leaving the conduit, passes over the sheaves 40, 41 supported in the bracket 42 arranged in the housing.

'' Referring again to the reach rod 20 the same is connected by link 43 to the cable 44 that passes over the sheave 45 arranged in the bracket 29 and to a hook 46 secured in a lever 47 fulcrumed to the aforesaid bracket 31 and spaced from the sectional lever30.

A cable 48 also connected to the said hook 46 passes over another sheave-in a submerged casing similar to the members 36, 35 but not here shown (being duplicates of these members) and through a conduit 49 into the housing 50 and about and between the sheaves 51, 52 arranged therein and is secured to the nonhinged end of the trigger 53 similar in all re- 55- direction. With the doors in closed position,

'spects to the trigger 39 except that its free end is disposed in the opposite direction to that of nected by the pin 58 and the inner end of said section 57 being made fast to the said axis extension 10. Made fast to the axis extension 14 is one end of one section 59 of the rotary sectional lever 59, 60, the meeting ends of said sections being pivotally connected by the pin 61 and the inner end of said section 60 being pivotally supported by the bracket 55.

An angular stop brackets 62 depends from the cross member 5 in the path of movement of the rotary sectional lever 56, 57 to limit the extent of movement thereof in one direction while angular lugs 63, 64 secured to the doors 1 2 adjacent their jambs and in the path of movement of one of the sections of each sectional lever arrest movement thereof in one illustrated in Figs. 5 and 6 the rotary levers 56, 57 or 59, 60 lie in a straight line drawn at right angles to the doors and passing through either bracket 54, or 55. The doors are therefore securely locked in closed position because any pressure against the doors from the inside tending to open them will be resisted by the said sectional levers. The doors may be opened, however, by a downward pressure exerted upon the outer end of the sectional lever 30.

In the closed position of the doors a pull is exerted upon the cable 34 that yieldingly retains the trigger 39 in housing 38 in raised position and a weight of approximately two hundred pounds must be applied to the raised or non-hinged end of said trigger to depress it. Depressing this trigger will depress the outer end of the lever 30 and cause cable 27 to pull upon the reach rod 15 which will pull upon reach rod 16 thus causing oscillation of the toothed segments 9, 11 in a common direction thus rotating the gears in mesh with said members and causing rotation of the extensions 10, 14 thus swinging the sectional le vers 56, 57 and 59, 60 inwardly or toward each other and so opening the doors 2 upon their hinges. The doors will swing open with considerable force until this movement is arrested by the same levers and as the sections thereof straighten out they will effectually resist any closing tendency of the doors caused by the wind or by a rebound action. The doors are now practically locked in open position:

against accidental closing.

The doors may be closed from inside the garage by depressing the lever 47 manually. The opening operation just described would have been caused by a vehicle moving toward the garage and a wheel thereof riding over the trigger 39 from the hinged or lower end there of. l/Vhen the vehicle is in the garage and the doors closed and it is not desired to have another vehicle open the doors again by running over the trigger the nut '32 of the sectional lever 30 will be moved toward the free end of said lever until that portion thereof connected to the cable 34 is freed from the cooperating section. The bolt portion engaged by cable 34 will then drop or move pivotally about its fulcrum substantially into parallelism with the door jamb and when the trigger 39 is again depressed the effect will be nil as the cable 34 has been slacked through this movement of the lever section. I

When a vehicle is inside the garage and it is desired to open the closed doors to permit departure the doors are opened by manually depressing the lever 30. As the vehicle leaves the garage one wheel will be caused to pass over the trigger 53 from the hinged end thereof thus, through the medium of the'cable 48, hook 46, lever 47 and cable 44 exertinga pull upon the reach rods 20, 21 and oscillating the toothed segments 9, 11 in a direction reverse to that caused by the rods 15, 16 thus causing the axis extensions 10, -14 to move the sectional levers 56, 57 and 59, 60 back to initial position at right angles to the doors and in Such movement the doors are, of course, closed by said levers.

What is claimed is 2-- 1. In garage door control mechanism, brackets secured to the garage doors, a cross member 'contiguous to the garage door opening, rotary shafts depending from said cross member, sectional levers fast to said shafts and pivotally engaging said rotary shafts, hand levers fulcrumed to the door amb for actuating said rotary shafts in opposite directions, one of said levers being of sectional formation, the sections thereof being separable, and Wheel operated means exterior to the doors connected individually to said hand levers whereby the same may be actuated.

2. In garage control mechanism, brackets secured to the garage doors, a cross member contiguous to the garage door opening, brackets secured to said member, meshing gears arranged in said brackets, the axis of one terminal gear in each bracket being extended, sectional levers fast to said extensions and pivotally engaging the first named brackets, connecting rods upon both sides of said meshing gears, the rods upon each side being connected together and to the remote gears of each bracket, hand levers fulcrumed to the door jamb and operatively connected to said connecting rods, and wheel operated means exterior to the doors connected to said hand levers individually whereby the same may be singly operated.

In testimony that I claim the foregoing as my own I have hereto affixed my signature.

MATT MATTSON.
